I have filtered out some outfits below. They are based off of reviews and images from other clients who have used them specifically for photos.
I recommend whites, ivory, creams, golds, coordinated with muted greens or reds. This is just to get you started, not a requirement. With these links below there are multiple colors so make sure you select the right one! Make sure to read reviews on sizing and look at the images.
As always, if you are doing family photos, coordinate your colors and mix the textures. Click here for a Pinterest inspiration board for more ideas: PINTEREST
